A method to reduce idle leakage power in I/O pins of an integrated circuit using external circuitry. Initially, I/O pins on a package are subdivided into those that will also remain powered up and those that will power down during idle state. When a system enters a low power mode, a signal is sent to the external circuitry. The signal notifies the I/O pins that always remain powered up to notify the external circuitry to power down the other set of I/O pins.

Reducing idle leakage power in an IC

An electronic control system that accurately maintains oscillation of an optical assembly at resonance. In the preferred embodiment, a signal control circuit delivers an input signal to an optical assembly. A resonance detector detects the difference in phase between the input signal and a feedback signal from the optical assembly. The phase difference is used to determine whether the optical assembly is at resonance. The signal control circuit is responsive to the resonance detector and modifies the frequency of the input signal to oscillate the optical assembly at its resonant frequency. The electronic control system can also maintain multiple optical assemblies at resonance.
